What are the symptoms of a vitamin B12 deficiency?
Vitamin B12 is stored in the liver for up to three years. The body can also draw on these reserves if there is a lack of vitamin B12 intake. In the meantime, a vitamin B12 deficiency usually only presents with general symptoms, such as:
- impaired mental and physical performance
- fatigue and exhaustion
- headaches and difficulty concentrating
- digestive problems
Over time, however, a vitamin B12 deficiency can lead to serious health problems. According to studies it may likely increase your risk for the following diseases:
- nervous disorders and depression
- cardiovascular diseases
What is vitamin B12?
vitamin B12 is a water-soluble vitamin, also called cobalamin. It is an essential vitamin, i.e. your body cannot produce it by itself and must get it from food. Vitamin B12 is the only water-soluble vitamin that the human body can store for long periods of time and occurs in various forms. The active forms that work in the body are methylcobalamin and 5-adenosylcobalamin.
Why do I need vitamin B12?
In the body, vitamin B12 is involved in the metabolism of folic acid, among other things. Folic acid is a B vitamin that works together with vitamin B12 in many places.
Vitamin B12 also plays a role in numerous other metabolic processes. Among other things it contributes to the following central processes in the body:
- formation of blood cells
- cell division
- protection of nerve cells
- formation of DNA
Where do I get vitamin B12?
vitamin B12 is almost exclusively contained in certain animal products, especially in offal, but also in other meats, fish, and dairy products as well as eggs. For example you can reach your daily requirement with 100 grams of tuna, 100 grams of lamb, 100 grams of natural yoghurt or two eggs.
Researchers are currently investigating whether vegetable foods can also serve as a source of vitamin B12. So far, however, they have only found the vitamin in so-called nori algae - and in a form that the human gastrointestinal tract cannot absorb. Thus, people who eat a vegan diet are currently only able to cover their requirements with vitamin B12 preparations.
How much vitamin B12 do I need?
The recommended daily intake of vitamin B12 varies considerably by country. In January 2019, the German Nutrition Society increased its recommendations and now advises adults to consume 4.0 micrograms of vitamin B12 per day. The US National Institutes of Health on the other hand, recommends only 2.4 micrograms. However, people's requirement differ depending on age and lifestyle.
Food supplements need to be taken in higher doses—because your body is only able to absorb and process part of the vitamin. The general recommendation is 500 micrograms a day to correct a deficiency. In the case of a severe deficiency significantly higher doses may be recommended, which are sometimes administered by physicians via injection.
